vation, and Fig.'3 a longitudinal-section, of a bench-plane provided with my invention. Fig.4 is a top view of the fircated lever of the mechanism for fastening the plane-iron in place in the stock and on the adjustable bed., Fig. 5 is a front view of the said ad-v justable bed.

The nature of my invention or improvement consists in the combination as well'as in the arrangement of an adjustable bed, and a mechanism, as hereinafter described, foi-'fastening the plane iron in place in the stock and v on the said bed, the parts of the said combination being arranged as hereinafter described, and the object or purpose of such invention being to enable the slant or inclination of the plane-iron to be varied in order to vary the width or size of the shavingmouth at the cutting edge of the planeiron, and thus adapt the plane to the cutting of either thick vor thin shavings from a piece of Wood or article while being planed.

In ythe drawings, A denotesy the planestock, provided with a throat, a., and a plane-iron, B, the latter having a cap iron or plate, C.

'Ihe planeiron rests on the lower part, b, of the throat a, and also on an adjustable bearing or bed, G,which is formed as shown in Figs. 3 and 5, screws into the stock, and is arranged in an inclined position, as exhibited in Fig; 3`. l

By taking hold of the head c ot' the bed or bearing G, and revolving the bearing, we can either screw it more of less into the stock, so' as to vary the distance of the top ofthe head from the upper surface of the stock.

In advance of the bearing G there is a screw, l), which goes through the plane-iron and its cap-iron, and is screwed into the stock. A forked lever, E, clasps the shank of the screw D, and directly underneath the head d thereof7 and has a screw, F, screwed through it and again-st the cap-iron G, the lower end of theisaid lever E being in contact with the cap-iron. l

The adjustable fulcrum-screw D, the furcated lever E, and the screw F, constitute the mechanism for fastening the plane-iron in the stock or in the latter and to the bearing G. This fastening mechanism I do not claim as my invmtion by its xlf, or irrespective of the adjustable bearing G.

By the use of the said fastening mechanism no wedge is required to hold the plane in the stock. Consequently there will be no danger of splitting the stock, such as is incident to the wedge. The adjustable bearin g G enables the shaving-month to be increased or diminished, as circumstances may require, and is also Aadvantageous in other respects.

I lay no claim to the invention ofthe mechanism as above described for fastening the plane iron in the stock, such mechanism consisting of the screw l), the lever E, and the screw F, arranged with respectto the planestock and the plane iron or irons as described. Nor do I claim an adjustable -bed as combined with stationary supports of the plane-iron,

'and constituting with them a means of conning the said plane-iron in its'place in the stock, the saine being as shown in Asahel G. Batchelders application for a patent tiled in United States Patent Uftice on or about the 3d day of July, A. D. 1857, and subsequently rejected. My invention not only differs from those above cited as Well in the structurel as j in the arrangement of its parts, but possesses one or more advantages not incident to them. In other words, while it retains all those ot the fastening mechanism above mentioned, itv

tage of not only varying the angle of inclination of the plane-iron, but of being capable of so springing the iron as to vary the breadth of the shaving-mouth of the throat as circumstances may require.

I claim- I the screw F, lthe planeiron B, and its bear; l. The combination of the adjustable bed ing b, arranged at the lower part of the throat or bearing G, the screws F and D, and the a, as described.

lever E the Whole being arranged with respeci; tf; the plane-iron and the stock snb- WING H TABDR' stantially as specied. Witnesses 2. The arrangement of the adjustable bed J. N. MARSHALL,
